Cov xim puv xim coj tau siv dav, tab sis txhua tus paub tsawg heev txog cov xim puv xim. Unit board tsis ua hauj lwm yog ib qho kev ua tsis tiav ntawm cov xim puv xim LED. Kuv yuav ua li cas thaum lub teeb puv xim coj zaub vaj huam sib luag ua tsis tiav?
Tag nrho cov xim coj zaub chav tsev board
1. Tag nrho cov vaj huam sib luag ntawm cov xim puv xim coj teeb lub rooj tsavxwm tsis ci: xyuas seb lub hwj huam mov thiab cov teeb liab kab txuas puas; xyuas seb daim npav pov thawj puas tuaj yeem paub qhov cuam tshuam; yog tias lub teeb liab ntawm daim npav pov thawj flashes, nws tsis tuaj yeem lees paub; xyuas seb lub teeb pom kev zoo txuas nrog daim ntawv pov thawj tib yam; xyuas seb lub teeb lub teeb yog tib yam li daim ntawv pov thawj; xyuas seb 74HC245 puas tsim nyog rau kev siv vuam siv hluav taws xob luv luv; xyuas seb qhov sib thooj ENable teeb liab tawm tswv yim / tso zis tus pin ntawm 245 yog qhov vuam virtual lossis luv luv.
2. Thaum scanning obliquely, cov kev cai stacking yog staggered thiab flashing dluab: xyuas seb puas muaj ib tug disconnection, virtual welding los yog luv luv Circuit Court ntawm lub teeb liab input ports a, b, c, d thiab lub teeb liab input chaw nres nkoj 245; kos cov cim a, b, thiab 245 c, d cov khoom siv hluav taws xob tau txiav tawm los yog soldered; xyuas seb lub teeb liab 245 puas raug txiav lossis soldered; xyuas seb cov teeb liab a, b, c, thiab d yog luv luv los yog seb lub teeb liab a thiab hauv av yog luv luv.
3. Yog hais tias ib los yog ntau txoj kab tau teeb tag, tsis muaj qhov ci: xyuas seb cov kab ntawm 138 thiab 4953 puas raug txiav, soldered lossis luv luv.
4. Thaum ua kev soj ntsuam sab hauv, teeb tsa ob lossis ntau kab nyob rau tib lub sijhawm (feem ntau yog ob zaug, txoj cai): xyuas seb cov cim A, B, C, D yog luv luv; xyuas seb qhov tso zis 4953 yog luv luv.
5. Thaum tag nrho cov xim LED zaub yog ci tag nrho, xyuas seb tus tswj tus pin ntawm cov khoom siv sib txuas yog luv luv, hloov lub module lossis ib lub teeb ci, thiab ib qho los yog ntau lub ntsiab lus tsis teeb (tsis xwm yeem).
